MustGrow Reports Significant Potato Yield Gains with TerraSante™

MustGrow Reports Significant U.S. Potato Yield and Economic Performance in Large Scale Field Trials Utilizing TerraSante™

Dec 10, 2025 | News Releases

• Mustard-derived organic TerraSante™ focuses on crop yields, soil and soil microbiome health, and nutrient/water use efficiencies;
• Large scale field trial showed 2 ton per acre yield increase with larger size potatoes and less culls equating to approximately US$5,000 increase in value per acre; and
• Significant soil health benefit when applied in combination with the current grower standard program.

SASKATOON, Saskatchewan, Canada, December 10, 2025 – MustGrow Biologics Corp. (TSXV:MGRO) (OTC:MGROF) (FRA:0C0) (the “Company” or “MustGrow“), a leading provider of biological and regenerative agriculture solutions, is pleased to announce outstanding performance metrics on its organic TerraSante™ biofertility product applied to potato farming acres in Washington State and Idaho, based on customer performance data.

In its use by a Washington State farming customer, TerraSante™ demonstrated a consistent and substantial potato yield, size, and quality increase at a dose rate of 11 lbs/acre. This customer performance data was generated on a large-scale commercial potato field. With the increase in size, quality and yield, the farmer estimated an approximate US$5,000 increase in value per acre at a cost of only US$180 per acre for TerraSante™. Work done in fields in Idaho has also shown significant benefits to the soil and health of the potato crops when used within a currently established grower production program.

These large-scale field trial results are consistent with small plot results that MustGrow has completed in the U.S. with TerraSante™.

MustGrow’s mustard-derived TerraSante™ organic biofertilizer is a soluble mixable form containing nutritious plant proteins and carbohydrates that feed the soil and soil microbes. TerraSante™ is currently registered and approved for sale in California, Florida, Arizona, Idaho, Oregon, and Washington State, under Organic OMRI Listed® certification and California’s Organic Input Material (OIM) Program.

In 2024, the United States Department of Agriculture (USDA) reported 927,000 potato acres harvested for US$4.6 billion of value sold.

TerraSante™ for Soil and Ecological Health
MustGrow’s biofertility program focuses on soil and soil microbiome health, nutrient and water use efficiencies, and plant yields. Soil is a farmer’s most valuable asset, and MustGrow’s mustard plant-based technologies are being applied with the intention to improve not only the health of the soil, but also the surrounding ecological environment.

TerraSante™, an organic biofertilizer in soluble mixable form, contains nutritious plant proteins and carbohydrates that feed the soil and soil microbes, potentially improving beneficial microbial activity and ensuring long-term sustainable soil health. These targeted micro-communities have been shown to work to improve nutrient availability, which can potentially increase plant vigor and yields, while reducing plant stress. TerraSante™ has the potential to improve crop nutrient uptake and, hence, overall crop performance. There are no artificial additives or preservatives used during its manufacturing.
